The Yellowjacks were a Royal Air Force aerobatic display team which flew Folland Gnat trainers painted yellow.

The team was formed in May 1964 by a group of flying instructors, led by Flight Lieutenant Lee Jones,[1] at No 4 Flying Training School at RAF Valley.

The two-seat Gnat T.1 had been in service at Valley only since November 1962, when the first 20 student pilots, selected after being awarded their "wings", from the recently graduated No 82 Entry of the RAF College Cranwell, had started their advanced training on the Gnat.

Instructors and student pilots loved this aircraft, because of its small size and its sensitive handling and high maneuverability.

The Red Arrows continued flying the Gnat until 1979 when it was superseded by the British Aerospace Hawk for the 1980 season.
